BALL-BEARING STOVE-LEG.

SPECIFICATION forming part of Letters Patent N 0. 712,122, dated October28, 1902.

Application filed June 14, 1902. Serial No- 111,619. (No model.)

To all whom it may concern.-

Be it known that I, OLAUS A. DAHL, acitizen of the United States,residing at Nash, in the county of Walsh and State of North Dakota, haveinvented certain new and useful Improvements in Ball-Bearing Stove-Legs;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as willena'ble'iothers skilled in theart to which it appertains to make and use the same.

My present invention has for its especial object to provide an improvedball-bearing foot for stove-legs; and to this end it consists of thenovel devices and combinations of devices hereinafter described, anddefined in the claims. a

The invention is illustrated in the accompanying drawings, wherein likecharacters indicate like parts throughout the several views.

Figure 1 is a view in side elevation showing a portion of a stove havingone of my improved ball-bearing feet applied to one leg thereof. Fig. 2is a horizontal section on the line 00 00 of Fig. 1. Fig. 3 is avertical section taken approximately on the line a 00 of Fig. 2, someparts being left in full. Fig. 4 is a transverse vertical section on theline x 00 of Fig. 3; and Fig. 5 is a view corresponding to Fig. 2, butwith some parts broken away and with the sections of the divided footdrawn apart.

The numeral 1 indicates a portion of a stove-body, and the numeral 2 oneof the legs thereof, which leg, as is customary, is cast hollow or ofangular form in cross-section.

The body of the foot is formed in two sections on at, having at oneendhalf-seats which closely fit a bearing-ball b, but permit the balls toproject below the foot and also, pref erably, above the same. The twosections'of the foot are clamped together by a short nutted bolt 0,which also clamps to the foot a .pair of laterally-spaced metal strapsf. The metal straps f are adapted to engage within the side flanges ofthe foot 2 and to be socured thereto by a nutted screw-bolt c. When thefoot (1 a is thus secured to the leg 2, the

forward portion thereof bears directly against the flange of the leg 2and the bearing-ball b of course rests on the floor. To give the ball I)increased traction or frictional engagement with the floor, it ispreferably provided with shallow grooves or scratches, as best shown inFig. 3. It will be noted that the inner end of the foot member a isformed .with a shoulder a and witha projecting lug 0. The shoulder aengages the inner end of the foot member a and holds the sections a afirmly against pivotal movements one with respect to the other.Preferably both of the sections a and a areprovided at their outer endswith upwardly-projecting lips or, which engage the lower end of the leg2 and assist in securing the foot against lateral movements with respectthereto. An anchoring-screw 9 works vertically through the lug a of themember a.

When the anchoring-screw g is screwed downward into engagement with thefloor, it is evident that the stove will be anchored in position asrigidly and probably more rigidly than in the ordinary construction,wherein the stove-legs set directly on the floor.

When the anchoring-screw is raised, it is of course evident that theball 17, or rather the balls of the several feet applied to the severallegs of the stove, make the moving of the stove over the floor or othersupport a very easy matter. V k The device above described is capable ofready application to stove-legs such as found in general use. It will,however, be understood that the device may be permanently secured tostove-legs or to legs of other devices in the process of manufacture.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is 'as'follows:

1. A detachable ball-bearing foot comprising a ball, a two-part footholding the ball and exposing the same for contact with the floor, and apair of metal straps connected to said foot and detachably securable tothe flanges of the stove-leg, substantially as described.

2. A detachable ball-bearing foot comprising a two-part footaa, thesection a of which has a shoulder a and lug a of the bearingball I) heldby half-seats formed in the two sections a a, the anchoring-screw gworking 100 vertically through said lug a the metal I In testimonywhereof I aflix my signature strapsfsecured to said foot bya nutted boltin presence of two witnesses. c, which bolt secures said sections a anda, l together, and the nutted screw-bolt 0' passed OLAUS DAIIL' 5throughsaid straps fand adapted to be passed Witnesses:

through the flanges of the stove-leg, substan- S. A. LEE, tially as andfor the purposes set forth. OLE OUVERSON.
